The Eye of Argon, by Jim Theis (TPB)

This is not a hoax. Jim Theis was a real person, who wrote The Eye of Argon in all seriousness as a teenager, and published it in a fanzine, Osfan in 1970.

But the story did not pass into the oblivion that awaits most amateur fiction. Instead, a miracle happened, and transcribed and photocopied texts began to circulate in science fiction circles, gaining a wide and incredulous audience among both professionals and fans. It became the ultimate samizdat, an underground classic, and for more than thirty years it has been the subject of midnight readings at conventions, as thousands have come to appreciate the negative genius of this amazing Ed Wood of prose.
